Uncompromising Security.

Signal Protocol Encryption

Every message, file, and call is secured with state-of-the-art end-to-end encryption. Keys never leave your device.

On-Device AI Detection

Our TensorFlow Lite models run entirely on your phone's processor, analyzing messages for phishing without sending data to the cloud.

Secure File Sharing

Share images and documents securely. Files are encrypted before leaving your device and decrypted only on the receiver's end.

Zero-Knowledge Relay

Our servers act only as a delivery mechanism. We store no plaintext data, and we cannot access your cryptographic keys.

Robust Authentication

Secure OTP-based identity verification coupled with local SQLCipher PIN protection ensures your account remains yours.

Advanced Safety Controls

Report suspicious actors directly to admins. Granular blocking and moderation tools keep the communication ecosystem safe.

Experience True Privacy.

Frequently Asked Questions

Yes. We use the Signal Protocol for End-to-End Encryption. Your messages are encrypted on your device and can only be decrypted by the intended recipient. We cannot read them under any circumstances.

Absolutely not. Aegis Chat uses TensorFlow Lite to run all threat detection models locally on your device's CPU/NPU. Your plaintext messages never leave your phone for analysis.

No. Our backend operates strictly as a zero-knowledge relay. It only handles routing encrypted ciphertext to the correct recipient. It has zero access to the decryption keys.

Aegis Chat was developed as a Final Year Project at Capital University of Science and Technology. Please check our GitHub repository (linked in the footer) for source code access and documentation.
